Usoro mmepụta nke Roba Roller-Nkebi 2

Ịmepụta

Akpụzi rọba na-abụkarị iji mado rọba mkpuchi na isi igwe, gụnyere usoro mkpuchi, usoro extrusion, usoro ịkpụzi, usoro ịgbanye injection na usoro ịgba ọgwụ.Ka ọ dị ugbu a, ngwaahịa ndị a na-emepụta n'ụlọ bụ n'ibu ma ọ bụ akwụkwọ ntuziaka ma na-akpụzi, na ọtụtụ mba ọzọ achọpụtala n'ibu akpaaka.Nnukwu na ọkara-sized roba rollers na-ihu ọma na-emepụta site profiling extrusion, na-aga n'ihu tapawa ịkpụzi site extruded film ma ọ bụ na-aga n'ihu winding ịkpụzi site extruding teepu.N'otu oge ahụ, na usoro ịkpụzi, nkọwa, akụkụ na ọdịdị ọdịdị na-akpaghị aka na-achịkwa microcomputer, na ụfọdụ nwekwara ike ịkpụzi site na usoro nke extruder ziri ezi na extrusion pụrụ iche.

Usoro ịkpụzi nke a kpọtụrụ aha n'elu nwere ike ọ bụghị naanị ibelata ike ọrụ, kamakwa wepụ ihe ndị nwere ike ime.Iji gbochie roba roba ka ọ ghara imebi n'oge vulcanization na iji gbochie ọgbọ nke afụ na sponges, karịsịa maka ihe mkpuchi rọba nke a na-akpụzi site na usoro mkpuchi, a ghaghị iji usoro nrụgide na-agbanwe agbanwe n'èzí.Ọtụtụ mgbe, a na-ekpuchi elu elu nke roba roba ma merụọ ya na ọtụtụ akwa akwa akwa ma ọ bụ akwa nylon, wee dozie ya ma tinye ya na waya ígwè ma ọ bụ eriri eriri.Ọ bụ ezie na emelarị usoro a, a ga-ewepụrịrị ihe mgbakwasa ahụ ka vulcanization gachara iji mepụta usoro "cecal", nke na-akpaghasị usoro nrụpụta.Ọzọkwa, iji akwa akwa na eriri ikuku dị oke oke na oriri dị ukwuu.imefusị ihe.

Maka obere na obere rọba roba, enwere ike iji usoro mmepụta dị iche iche, dị ka patching akwụkwọ ntuziaka, ntinye extrusion, nrụgide injection, injection na ịwụsa.Iji meziwanye mmepụta mmepụta ihe, a na-eji ọtụtụ n'ime usoro ịkpụzi ihe ugbu a, na izi ezi dị elu karịa nke usoro na-abụghị nke ịkpụzi.Nrụgide injection, injection nke rọba siri ike na ịwụsa rọba mmiri mmiri aghọwo ụzọ mmepụta ihe kachasị mkpa.

Vulcanization

Ka ọ dị ugbu a, usoro vulcanization nke nnukwu rọba na-akpụ akpụ na nke ọkara ka bụ vulcanization tank vulcanization.Ọ bụ ezie na agbanweela ọnọdụ nrụgide na-agbanwe agbanwe, ọ ka naghị apụ apụ na ibu ọrụ dị arọ nke njem, ibuli na ibutu.Isi iyi ọkụ vulcanization nwere ụzọ kpo oku atọ: uzuoku, ikuku na-ekpo ọkụ na mmiri ọkụ, na isi ihe ka bụ uzuoku.The roba rollers na pụrụ iche chọrọ n'ihi na kọntaktị nke metal isi na mmiri vepo nakweere indirect uzuoku vulcanization, na oge ga-adị ogologo site 1 ka 2 ugboro.A na-ejikarị ya eme ihe maka ndị na-akpụ akpụ rọba nwere cores ígwè oghere.Maka ndị na-akpụ akpụ rọba pụrụ iche nke a na-apụghị iji tankị vulcanizing mee ihe, a na-eji mmiri ọkụ eme ihe mgbe ụfọdụ maka vulcanization, mana ọgwụgwọ nke mmetọ mmiri kwesịrị ka edozi ya.

Iji gbochie rubber na isi ígwè ahụ ka ọ ghara imebi ya n'ihi nkwụsị dị iche iche nke okpomọkụ conduction dị iche n'etiti roba na roba isi, na vulcanization na-emekarị na-anabata a ngwa ngwa kpo oku na nrụgide usoro mmụba, na vulcanization oge dị ukwuu. ogologo oge karịa oge vulcanization nke rọba n'onwe ya chọrọ..Iji nweta otu vulcanization n'ime na n'èzí, na ime ka thermal conductivity nke metal isi na roba yiri nke ahụ, nnukwu roba roba na-anọ na tank maka awa 24 ruo 48, nke bụ ihe dịka 30 ruo 50 ugboro oge ịgbagha roba. .

Ndị obere rọba na obere obere na-agbanwe ugbu a ka ọ bụrụ efere vulcanizing press molding vulcanization, na-agbanwe kpamkpam usoro vulcanization ọdịnala nke rollers rọba.N'afọ ndị na-adịbeghị anya, a na-eji igwe na-akpụzi injection wụnye ihe na-emepụta ihe na oghere vulcanization, na enwere ike imeghe ma mechie ya na-akpaghị aka.A na-emeziwanye ogo nke igwe na akpaaka nke ukwuu, na oge ịgbapụ dị mkpirikpi, mmepụta mmepụta dị elu, na àgwà ngwaahịa dị mma.Karịsịa mgbe ị na-eji igwe na-emepụta ihe na-emepụta ihe na-emepụta roba, a na-ejikọta usoro abụọ nke ịkpụzi na vulcanization n'ime otu, na oge a ga-ebelata ka 2 ruo 4 nkeji, nke aghọwo ihe dị mkpa ntụziaka maka mmepe nke roba mmepụta.

Ka ọ dị ugbu a, roba mmiri mmiri nke polyurethane elastomer (PUR) na-anọchi anya ya etolitela ngwa ngwa na mmepụta nke rollers rubber, ma meghee ụzọ ọhụrụ nke ihe na usoro mgbanwe maka ya.Ọ na-akwado ụdị ịwụ ahụ iji kpochapụ ọrụ ịkpụzi dị mgbagwoju anya na akụrụngwa vulcanization buru ibu, na-eme ka usoro mmepụta rọba dị mfe.Otú ọ dị, nsogbu kasịnụ bụ na a ghaghị iji ihe ọkpụkpụ mee ihe.Maka nnukwu rollers roba, karịsịa maka ngwaahịa ndị ọ bụla, ọnụ ahịa mmepụta na-abawanye nke ukwuu, nke na-eweta nnukwu ihe isi ike na nkwalite na iji.

Iji dozie nsogbu a, usoro ọhụrụ nke PUR rubber roller na-enweghị mmepụta ihe apụtawo n'afọ ndị na-adịbeghị anya.Ọ na-eji polyoxypropylene ether polyol (TDIOL), polytetrahydrofuran ether polyol (PIMG) na diphenylmethane diisocyanate (MDl) dị ka akụrụngwa.Ọ na-eme ngwa ngwa mgbe agwakọtachara ma kpalie ya, a na-awụsa ya n'ụba n'ime isi igwe rọba na-agbagharị nwayọ nwayọ., A na-achọpụta nzọụkwụ site na nzọụkwụ mgbe ị na-awụsa ma na-agwọ ya, n'ikpeazụkwa, a na-emepụta roba roba.Usoro a abụghị naanị mkpụmkpụ na usoro, dị elu na mechanization na akpaaka, ma na-ewepụkwa mkpa maka nnukwu ebu.Ọ nwere ike ịmepụta rollers rọba nke nkọwa na nha dị iche iche na ọchịchọ, nke na-ebelata ọnụ ahịa nke ukwuu.Ọ ghọwo isi ntụziaka mmepe nke PUR roba rollers.

Tụkwasị na nke ahụ, ihe ndị na-emepụta ihe na-emepụta ihe na-emepụta ihe na-emepụta ihe eji arụ ọrụ ụlọ ọrụ na mmiri silicone roba na-etolite ngwa ngwa n'ụwa nile.E kewara ha ụzọ abụọ: ọgwụgwọ ikpo ọkụ (LTV) na ọgwụgwọ okpomọkụ (RTV).Ngwa eji eme ihe dịkwa iche na PUR dị n'elu, na-eme ụdị nkedo ọzọ.N'ebe a, okwu kachasị mkpa bụ otu esi ejikwa ma belata viscosity nke ogige roba ka o wee nwee ike ịnọgide na-enwe ụfọdụ nrụgide na extrusion ọsọ.
